ALX System Engineering Plus

Studies carried out in the ALX Software Engineering Plus course

Technologies

• Bash: 5.1-6ubuntu1
• Docker: 24.0.5
• GCC: 9.4.0
• Ubuntu: 20.04 LTS

Concepts

• Expected is an understanding of the following concepts:
  • Agile Teams
  • Pair Programming
  • Flowcharts

Resources

• Expected is a consumption of these resources:
  • Secrets of printf
  • printf (3)

Project Requirements

• Allowed editors:

  • vi
  • vim
  • emacs

• All source code:

  • To be compiled on Ubuntu 20.04 LTS, with gcc as the compiler of choice, using the options
    • -Wall -Werror -Wextra -pedantic -std=gnu89
  • To have prototypes to be placed in a header
    • Name the header, main.h
    • Ensure that header is included guarded
  • To have no more than 5 functions per file
  • To end with a new line
  • To have no errors and no warnings during compilation
  • To use the Betty style.
  • To have it's best practices checked using betty-style.pl and betty-doc.pl
  • Global variables are disallowed

• ALX will using its own main.c files at compilation, which may be different from the ones shown in the examples

• A README.md file at the root of the repo, containing a description of the repository

Authorized functions and macros

• Memory management:

  • malloc (man 3 malloc)
  • free (man 3 free)

• Output

  • write (man 2 write)

• Variadic Argument handling

  • va_start (man 3 va_start)
  • va_end (man 3 va_end)
  • va_arg (man 3 va_arg)
  • va_copy (man 3 va_copy)

Compilation

• Code will be compiled this way:

   $ gcc -Wall -Werror -Wextra -pedantic -std=gnu89 *.c
  

• As a consequence

  • Be careful not to push any c file containing a main function in the root directory of your project (you could have a test folder containing all your tests files including main functions)
  • Our main files will include your main header file (main.h): #include main.h
  • You might want to look at the gcc flag -Wno-format when testing with your _printf and the standard printf
  • We strongly encourage you to work all together on a set of tests
  • If the task does not specify what to do with an edge case, do the same as printf
